Some network devices need proper reinitialization before they can be
used. This is especially the case when using devices that share the same
driver.
Therefor the current approach, starting the open routine of an ether
device just once with the first call of send, runs those devices into
some unreliable behaviour.
This patch disables all devices that are not being used so they get
reinitialized with the next usage.
